It just keeps contaminates out and lube in. IE road grime. You can replace it with any similar boot. I'd clean and regrease the yoke while you're in there, some simple grease usually works. Some people use anti-seize.

 

I already greased it. Lol.

 

that rear o2 doesn't affect the engine btw except a cel.

 

I know but I still like to have it.

 

Ok so, there's coolant residue around where the radiator cap goes, and beneath the thermostat housing. If these are leaking pressure you guys think it could allow the temp to get hotter than normal?

 

Honestly, a leak shouldn't affect it that badly, unless it is pouring coolant out (as long as the system keeps decent pressure, the fluid should be moving normally). It could be leaking due to the increased pressure of water being at 230*F vs 210*F

How long ago was the pump replaced? IMO, I would replace the thermostat and radiator cap and see if it improves. Maybe do the water-pump gasket and put some thread sealant on the heater-core pipe. Check the pump and make sure the bearings feel good and everything. I always drill a tiny hole at the top of the thermostat to make it easier to bleed air out of the system. Felpro gaskets on the waterpump and thermostat housing have not leaked for me.

You need a fan shroud though, if you are sitting in traffic the fan is basically going to blow hot air around the motor, instead of pulling cool air through the radiator. It is so cheap I would just order one instead of shlepping myself to the Junkyard and dealing with the U-Pull-And-Pay arseholes

Have you tried cleaning your condenser/radiator? (degreaser + a hose is sufficient)
Doubt it will help, but surely won't hurt.

EDIT:
Be very careful - 230*F is in the territory of warping/cracking the head, or blowing a coolant hose off or something.

 

Replaced radiator cap and tightened the lower thermostat housing bolt, let it idle in the sun for 30 mins with AC on, didn't even break 220.

 

Glad you're getting closer, I think 220s not that bad for hot out with ac on at idle.

 

I'm gonna assume the shroud will be enough to fix it and keep it cool. I don't feel like replacing the water pump or radiator.
I'll found out for sure in my coming trip to Texas. Lol.

Once again, thanks for all y'alls help, I truly do appreciate it.

Marine,don't take this on a trip until you get the shroud on.

 

My trip isn't for a couple weeks, I'll have the shroud tomorrow. Don't worry, I wouldn't do that.

 

Why don't you feel like replacing those parts? Cost or time or what? They are very simple to do and don't cost much. You've done most of the cooling system I would just do it all and know it's in tip top shape instead of just hoping and praying

 

They were done with proof just over a year ago, I see no reason to replace them at this point. The radiator nor the water pump is leaking.

 

When I did my radiator replacement a few years back I went cheap. It wasn't leaking but it sucked at its job. If you didn't do the replacement, the precious owner probably cheaper out on parts just to sell it. I would get higher quality parts and do it again so I absolutely know that those parts aren't the problem

 

I was worried it was a cheapie, it's a mopar radiator.
